Professional Applications & Engineering Value
This nylon flat washer delivers critical engineering solutions where electrical insulation and corrosion resistance are paramount. The white nylon plastic construction eliminates galvanic corrosion between dissimilar metals while providing reliable isolation in electrical enclosures, control panels, and communication equipment. Its NAS1515-H04 compliance ensures precise dimensional stability for consistent performance in aerospace, automotive, and industrial applications. The material's inherent non-conductive properties prevent electrical shorts, while its chemical resistance protects against degradation from oils, solvents, and moisture. These characteristics make it ideal for No. 4 screw assemblies requiring lightweight, durable spacing and protection without metallic contamination.
Specification Summary & Compliance
This flat washer features precise inch system dimensions with 0.125" inner diameter, 0.312" outer diameter, and thickness ranging 0.053-0.073". Manufactured to NAS1515-H04 specifications for consistent quality and performance. The washer is RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant with current SVHC documentation, meeting international environmental standards. Designed specifically for No. 4 screw size applications with temperature resistance up to 180°F maximum operating temperature.
